WASHING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed May 4, 1910. Serial No. 559,357.

' washing machines and its object is to provide a machine for thepurpose so constructed as to perfect and facilitate the operation ofwashing, the articles to be washed being passed through the machine withan intermittent movement and out between wringing rolls, suitable meansbeing provided within the machine for working out the dirt.

A further object is to provide certain other new and useful features inthe construction and arrangement of parts all as hereinafter more fullydescribed reference being had to the accompanying drawings in which,

Figure 1 is a side elevation of a device embodying the invention; Fig. 2is a longitudinal .vertical section through the same; Fig. 3 is atransverse section substantially on the line ac-m of Fig. 1; Fig. 4 is asimilar section substantially on the line yy of Fig. 1; and Fig. 5 is aplan view of the machine.

As shown in the drawings 1 represents a suitable tank or receptacleadapted to contain water supported upon suitable legs 2. Secured to eachend of the tank 1 are brackets 3 forming bearings for small rollers 4and 5 and mounted within the tank adjacent to each end thereof are twopairs of rollers,- a pair of feed rollers 6 at the forward end of thetank and a pair of wringing rollers 7 at the rear of the tank, the lowerroll 8 of each pair being mounted in bearings upon the inner sides ofthe walls of the tank and the upper roll 9 of each pair being mountedupon a shaft 10 which is extended through vertical slots in the sidewalls of the tank to move freely therein. A. collar 11 is provided onthe shaft 10 of each roll adjacent to the outer side of the walls of thetank and to these collars are attached coiled springs 12 at one end, theopposite ends of said springs being secured to pins projecting from thesupporting frame of the tank. These springs thus exert a force to holdthe rolls 8 and 9 in yielding contact with each other and the pair ofrolls 7 at the rear end of the machine is preferably provided with acovering 13 of rubber or other suitable yielding material so that theserolls will serve as wringing rolls when the clothes pass between themand out of the rear end of the machine.

To feed the garments to be washed through the machine, two endless beltcarriers are provided, the lower belt 14 passing over the roll 4 on thebracket 3 at the for ward end of the machine and upward at aninclination through the end wall of the tank and between the feed rolls6, thence along the bottom of the tank beneath an idler 15 adjacent tothe pair of rolls 7, then outward between said pair of rolls through therear end of the tank and downward over the roll 4. The lower run of thecarrier passes over idlers 16 and 17 mounted in bearings on the legs 2some distance below the bottom of the tank and the portion of thecarrier between the pairs of rolls within the tank is preferably leftslack so that it will lie upon the bottom of the tank. An upper endlesscarrier belt 18 passes over the roll 5 on the bracket 3 at the forwardend of the machine and between the pair of rolls 6, thence through themachine beneath the idler 15 and out at the rear end of the machinebetween the pair of rolls 7 and upward over the roll 5. The run betweenthe roll 5 at the rear end of the machine and the similar roll at theforward end of the machine passes over and is supported by idlers 19 and20 mounted in open bearings in bracket arms 21 extending upward from theside walls of the tank. The portion of the carrier between the feedrolls 6 and the wringing rolls 7 within the tank is left slack the sameas the similar portion of the carrier 14 so that the articles tobewashed which are fed in between the feed rolls 6 upon the inclinedportion 22 of the belt 14 will lie between the two slack portions of thetwo belts within the tank, free to change their position and spread outso that they will be subjected to the action of the water 7 and a seriesof heaters 23 in the tank.

T0 beat or pound the clothes as they are fed through the tank upon itsbottom by the carrier belts, a series of transverse strips 23 areprovided, these strips being set on edge in parallelism and guided intheir vertical movement by suitable guides 24 on the inner face of theside walls of the tank. T0

raise and lower these beaters so that they will beat or pound thearticles to be washed, a carrier is provided consisting of alongitudinally extending bar 25 supported within the tank near the topthereof by transverse bars 26 and 27 to which the longitudinal bar isfirmly secured at its upper edge. Each beater 23 is attached to the bar25 by a rod 28 having a hooked lower end engaging a bearing loop securedto the upper edge of the beater at its center. The rod passes upwardthrough suitable bearing clips secured to the side of the bar 25 andthrough bearings in a bracket 29 on the upper edge of said bar, free toslide in said bearings; Sleeved upon the rod between the upper end ofthe bracket 29 and a collar 30 secured to the rod is a coiled spring 31,and thus when the bar 25 is lowered to lower the beaters and saidbeaters come in contact with material in the tank, said beaters may risea short distance against the action of the springs 31 and by pivotallyattaching the beaters to the bar 25 by means of the rods 28, saidbeaters are free to move upward at either end or tilt, but are guided atall times in their vertical movement by the guides 24 on the side wallsof the tank.

T0 actuate the beaters by raising and lowering the bar 25, two parallelshafts 32 and 33 are mounted in bearings upon the bottom of the tank andextend transversely thereof, said shafts being provided at each end witha crank arm 34 or other member serving the purpose of a crank and motionis transmitted from the crank arms to the bars 26 and 27 by means ofconnecting rods 35 attached at their upper ends to the ends of the barsand at their lower ends to the crank arms or their equivalents. Power isapplied to turn one of the shafts by means of a belt 36 or power may beapplied thereto in any other convenient manner, and motion istransmitted from said shaft to the shaft 33 by means of a belt 37running over pulleys upon said shafts and these pulleys 38 may serve ascrank arms for attaching the connecting rods 35 to the shafts byattaching the lower end of said rods to the pulleys.

The upper roll 9 of the pair of feed rolls 6 and the similar roll of thewringing rolls 7, are positively turned to feed the carriers 14 and 18,by swinging arms 39 pivotally mounted intermediate their ends upon theshafts 10 of said rolls and pivotally attached to the upper ends of saidarms 39 are dogs 40 to engage ratchet wheels 41 secured upon the shaft10 adjacent to the collars 11. Secured upon the shaft 33 adjacent toeach side of the tank is an eccentric 42 engaged by an eccentric strap43 carried by an arm 44 pivotally attached at its upper end to the sideof the tank. Connecting rods 45 con nect the lower ends of the arms 39with the lower ends of the straps 43 and thus when the shaft 33 isturned the eccentrics 42 will swing the arms 44 and the arms 39 will beturned by the connecting rods 45, and actuate the shafts 10 with a stepby step movement through the medium of the ratchet wheels 41 engaged bythe dogs 40 carried by the said arms. The carrier belts are thus fedthrough the tank with a slow step by step movement carrying the clothesbeneath the beaters within the tank which beaters are given acomparatively rapid actuation by the cranks on the shafts 32 and 33. Bypositively driving the pair of rolls 6 and also the pair of rolls 7 theslack in the two carriers within the tankis maintained and the outerruns of said carriers are drawn tight so that the inclined portion 22 ofthe carrier 14 forms a moving table upon which the articles to be washedare placed and spread out so that they will be carried through by thecarriers and properly subjected to the action of the water and thebeaters. The extended inclined portion of the carrier 14 at the rear endof the machine corresponding to the portion 22, also forms a movingtable upon which the clothes pass out from between the wringing rolls 7.

Having thus fully described my invention what I claim is 1. A washingmachine comprising a tank, a series of vertically movable transversebeaters within the tank near the bottom thereof, a longitudinal bar towhich the heaters are yieldingly attached, a transverse shaft beneaththe tank, eccentrics on said shaft, means for imparting a verticalmotion to the longitudinal bar from said eccentrics, two endless carrierbelts having mating slack portions within the tank upon the bottomthereof beneath said beaters, one of said belts extending beneath thetank and the other above the tank, a pair of mating rolls at each end ofthe tank between which the belts extend for positively driving the same,a ratchet wheel to drive one roll of each pair, levers, pawls on saidlevers engaging the ratchets, and means connecting said levers toactuate the same simultaneously.
